Power amplifier meets WiMAX needs

The AP3011 covers the key frequency ranges specified for WiMAX applications, from 2.3 to 2.7GHz.

Admiral Microwaves has released a power amplifier designed to meet the demand for components complying with the upcoming WiMAX standard.

Designed and developed by RF Integrated Corporation (RFIC), the AP3011 covers the key frequency ranges specified for WiMAX applications, from 2.3 to 2.7GHz.

This is the most popular band for WiMAX technology systems in the US and most Asian and European countries.

WiMAX is also expected to expand rapidly in many developing countries with a poor wired or broadband infrastructure.

It will be incorporated into handheld devices once the standard is fully deployed.

Primary applications for the power amplifiers include IEEE802.11b/g and 2.4GHz ISM Band wireless systems, as well as IEEE802.16 (WiMAX) systems.

In addition, they will prove useful in a range of high-power WLAN applications.

The AP3011 is a linear, three stage power amplifier with high output power in the 2.3 to 2.7GHz band and very stable performance throughout the whole bandwidth.

With excellent linearity and high gain from 30.5 to 35dB, the device delivers 22.5dBm output power at data rates up to 54Mbit/s, with OFDM modulation and 3% EVM at 3.3V.

Also suitable for IEEE802.11g schemes, it offers 26dBm linear power at 5V.

The power amplifier includes an on-chip power detector which provides a DC voltage proportional to the output power of the device.

These power amplifier MMICs are fabricated using an InGaP/GaAs HBT process and are supplied in 3 x 3mm, 16-pin, QFN leadless packages.
